This class represents an aircraft yaw rotation action to be scheduled on the Mission Control timeline. By creating an object of this class and adding it to the timeline, an aircraft will rotate around yaw by the specified angle with the specified speed when the Timeline reaches the action.
Initialize with a yaw angle relative to current heading or absolute heading against true north. The range of angle is [-180, 180]. This initializer should be preferred when accuracy of the angle is more of a priority than smooth yaw movement.
Angle in degrees.
YES means angle is the absolute heading against true north. NO means angle is relative to the current heading.
